Cogswell 1949 Contopus ruficollis Aug.8-19. Big Lagoon, Humboldt Co., Calif. Fairly common in spruce-alder forest, Riparian (alder, willow) woodland & border of these with grassland. Also noted in Spruce-fir forest and in 3-year old burn. Full "pee-yeeer" calls given all thru this period. Aug.21 French Camp, 3100 ft., Humboldt Co., Calif. - I heard calling in Douglas fir forest. Aug.24 I seen together in Douglas fir-Tan Oak forest with considerable understory. This species has been unexpectedly rare at this camp. Aug.29-30 1/2 mi. N Yellow Creek, 400 ft., Humboldt Co., Calif. one adult, giving full "song" ("peeeewr"), and one young one apparently begging food from the adult with a wheezy "preeee". I did not see the adult feed it, but the 2 were followed thru several adjacent walnut trees of an old orchard. Aug.31 I collected 1 (*92) from the Bay-Cottonwood-Oak woodland strip bordering the Trinity River near this same orchard.
